CHURN.

SPECIFICATION forming part of Letters Eatent No. 638,598, dated December5, 1899.

Application filed September 6,1899. Serial No. 729,693. (No model.)

To all whom it may concern.-

Be it known that I, VIOLA J. ROBERTSON, a citizen of the United States,residing at Weatherford, in the county of Custer and Territory ofOklahoma, have invented certain new and useful Improvements in Churn's;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to improvements in churns, and more particularlyto that class known in the art as reciprocating body-work ers; and theobject is to simplify and improve the construction and increase theefficiency of the churn with a minimum expenditure of power.

To this end the invention consists in certain features of constructionand combination of parts, which will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a perspective View of myimproved churn. Fig. 2 is a longitudinal section of the same. Fig. 3 isa transverse central section.

In the drawings the same reference characters indicate the same parts ofthe invention.

1 1 denote the parallel base-plates, which support the longitudinal arch2, and 3 3 denote the transverse parallel stirrups, mounted in the archand having their lower ends terminating in the lateral toes 4 4, whichare pivoted in the longitudinal side. rails 5 5, the ends of which carrythe vertical uprights 6 6, which support the longitudinal bench 7, and 88 denote limit-straps extending from the outer ends of the bench to thebase-plates to limit the movement of the bench in either direction.

The upper face of the bench is formed with a pocket 9 to receive thechurn-body, which snugly fits between the parallel shoulders 10 10,forming the transverse parallel end walls of the pocket.

The churn is provided with a removable screw-cap 12 and with guide-eyes13 13 to receive the straps 14 14, fixed to the side edges of the benchand adapted to removably secure the churn-body in place.

From the manner in which the bench is swung from the arch it will beseen that the bench and churn are capable of having two independentmovementsa longitudinal re= ciprocating movement to churn the cream andbring the butter and a lateral oscillating movement to axially rock thechurn-body and collect the butter.

It will of course be understood that various changes in the form,proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this in= vention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

In combination, the transverse base-plates, the longitudinal archsupported in said baseplates, the transverse stirrups centrally pivotedin said arch, the longitudinal parallel side rails pivoted in the lowerends of said stirrups, the vertical uprights fixed to said rails, therecessed bench fixed to said uprights, the limit-straps connecting theends of the bench and base-plates, and the transverse retaining-strapsfixed to the side edges of the bench and extending across the pocket,substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
